IIR document
A phase-field approach for two-fluid flow simulations.
Author(s) : STALIO E., MENCINGER J., ZUN I.
Summary
A phase-field approach is presented for the numerical simulation of two-fluid forced flow in channels. The difference in physical properties of the two components is handled following a quasi-incompressible approach. The axisymmetric from of the Navier-Stockes and Cahn-Hilliard equations system is solved, and the numerical results presented consider a narrow pipe of radius R= 1 mm, where buoyancy effects are neglected. Results of three simulations for the evolution of spherical and elongated hexane bubbles in water for Re= 220 and We= 96 are reported.
